Science Experiments - Kids Preschool Science

Science experiments for kids and preschool science activities can be fun for children. Science is about doing and observing. Sometimes it may involve all of our senses, touch, taste, sight,smell and hearing. Preschool science activities do not always have to be complicated.

Preschool Science Activity: Melting

preschool science experiment

2 large bowls or bins
2 large chunks of ice or snow
Coarse Salt or industrial salt for melting outdoor ice
Chart Paper
Marker

What to do for this science experiment

Fill the two bins with the snow or ice. Ask the children who thinks the ice alone will melt more quickly, and how many children think the ice with the salt will melt more quickly. Document their answers on chart paper. Dump a handful or two of salt onto the ice in one of the bins and wait to see what happens.
Document the end result and compare it with the children’s answers.

How does salt make ice melt more quickly?

Answer: When the ice starts to dissolve it changes the temperature in the ice slightly, causing it to start melting faster than ice just sitting on its own.

(Same answer if using snow instead of ice).
